At the Lego display, swarming children sifted through Lego blocks of all sizes and colors to make creations.

“We love to give all kids an opportunity to have the experience of building and creating something. They get to put it on display and get their picture taken with it,” Lego senior analyst Tara A. Moser said. “The adults come in and they get excited. They remember the memories they had when they were kids.”

Gina Smith, of Suffield, enjoyed pizza from Randy’s Wooster Street Pizza Shop as her son Caleb Roy, 8, made a Lego paddleboat.

“The kids enjoy it. It’s nice to see what we have in this state,” Smith said.

Over at Pez central, Marcus Smith, of Torrington, Conn., was helping his son, Danny, 4, pick out a Pez dispenser. Danny was torn between Thomas the Tank Engine and Lightning McQueen.

Smith said his favorite state building is Vermont - he likes the food and the beer there.

Over in Vermont, Timothy J. Wallace and his daughter Brittany M. Wallace, 17, just finished picking up some “strong sharp cheese and horseradish.”

Before he goes back home to Groton, Conn., he revealed that he always buys cheese in Vermont. He also was first in line to buy flannel pajama shorts from the Vermont Flannel Co. He said the price went up to $24.80 this year, but said he feels the quality is well worth it.

“Every year I get a pair. I wait for this building to open,” Wallace said.

Brittany was going to buy maple cotton candy.

“We go nuts,” her father said.

In Maine, the line for the baked potatoes was long, but Amy Schumaker of Cleveland, Ohio, said she only had to wait 10 minutes. It was her first time sampling the popular Maine baked potato, something friends told her she had to try.

“It was worth the wait,” Schumaker said.

“It’s one of the reasons why we came early,” chimed in Robert Schumaker.

In Massachusetts, local companies were well represented, including Granville Country Store, Thorndike Mills in Palmer and Nourse Farms in Whately, which featured different varieties of fresh raspberries.

Jon Sandoval, of Hebron, Conn., munched on raspberries from Nourse. He said he is a “big fan” of raspberries.

“They’re delicious. It’s nice to see what every state has to offer. We just came from Rhode Island, where we had Del’s lemonade. We’re going to Maine next for baked potatoes,” Sandoval said.

Rhode Island building manager Jayne E. Panarello said visitors usually “blow right past me and head for the chowder and clam cakes in back.”

That’s where Lee and Tom Carraher, of Auburn, were. They were eating shrimp and corn chowder from Kenyon’s.

“It’s awesome,” Lee said.

In New Hampshire, Carol E. McShane brought in members of the robotics 4H youth group, “Rogue Robots.” They are from New Hampshire and McShane said she is partial to the building.

“I love watching the kids feel some pride in where they come from,” McShane said.

At the corn on the cob booth, Ricky D. Blye said the corn is picked fresh daily every morning and brought to the fair. He said 65 dozen ears were sold on Friday. Last year, they sold more than 14,000 ears over the fair’s three-week run.

His mother, Lynne Blye, runs the New Hampshire building. She said the corn comes from a Mason farm that grows a special field of late corn just for the Big E.

Christian Cotham, 12, who was visiting from Florida, said he liked his first Big E experience.

“It’s like a flea market, except bigger,” Cotham said.

The fair runs through Sept. 30. Information can be found at www.thebige.com
